    <span style=”background-color: rgba(255, 255, 255, 0);”>Hello Ian

    I have had a chance to use a Dyno
    To test my cr250 based engine after getting a good baseline. I put carb (38mm mikuni )on flow bench got a baseline. Then taper bored and worked the bell area. To a 20% increase .
    Re installed on engine and. Reran  the pulls. And the graph layed right over the first runs
    So next I put a 44mm on just to see.  And it did same!!!
    Now I’m confused  (I have V force reeds).  Is that the limit of motor or is there a restriction I need to be looking for?   Any ideas
    Thanks in advance
